"Talking to you, I have smelled alcohol on your breath," Burnett told Nunberg.

"Well, I have not had a drink," Nunberg replied.

"Because it is the talk out there — again, I know it's awkward — let me just give you the question so you can categorically answer," Burnett said. "No, you haven't had a drink today?"

"My answer is no, I have not," Nunberg said.

"Anything else?" Burnett asked.

"No, besides my meds," Nunberg said. "Anti-depressants. Is that OK?"

The interview was one of several Nunberg gave Monday, including one with USA TODAY and at least three with CNN.

Nunberg consistently said he was willing to risk arrest to skip a scheduled appearance before a grand jury. He also said he would not give investigators old campaign emails, which he has been ordered to hand over in a subpoena.

Nunberg also said he thinks President Trump "may have done something during the election" based on the questions Mueller asked him and that former Trump campaign adviser Carter Page had likely colluded with Russians meddling in the 2016 election.

White House press secretary Sarah Sanders said Nunberg was "incorrect" and said he clearly lacks knowledge on the subject.

TheDaily Beast reported that several of Nunberg's friends were concerned he had been drinking before the interviews.

Several close friends of former Trump adviser Sam Nunberg told me they had strong reason to believe he was day-drunk during his cable-news blitz today based on conversations he had with them starting this morning: https://t.co/cfR6uOqxbJ
